' HARRY A. SCHWARTZ, OF DEFIANCE, OHIO, ASSIGNOR TO DEFIANCE IACHINE WORKS, OF DEFIANCE, OHIO, A

CORPORATION OF OHIO.

AUTOMATIC CEUCKING MACHINE.

/ .Application filed July 12,

To all whom it may concern:

Be it known that I, HARRY A. SoHwAR'rz,

' a citizen of the United States, and a resident of Defiance, in the county of Defiance and State of Ohio, have invented a new and Improved Automatic Chucking Machine, of

.which the following is a full, clear, and

like, according to requlrements and without -at one face and at the sides in a predeterrequiring change of the position of the work in the work holder.

Another object is to permit of operating on a plurality of pairs of castings at a time mined sequence and without requiring adjustment or handling of the castings.

Another object is to turn out a large number of finished articles in a comparatively short time.

The improved automatic chucking machine in the embodiment shown in the drawings and hereinafter described in detail is designed for doing twenty-one different tooling operations on each of a pair of companion (right and left) cam shaft brackets, such as are used on internal combustion engines for'automobiles, but I do not limit =myself to this particular arrangement of the machine as the latter can be used with the same or with different tools for performing other tooling operations besides the ones shown and hereinafter specifically described without deviating from the spirit of my invention, it being understood that I reserve the right to resort to embodiments other than the'one actually illustrated here-' in to the full extent indicated by the general meaning of the terms .in which the claims are expressed and by variations in the phrasing of the same.

' WVith these and other objects in view, the

invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying draw- Specification of Letters Patent. Patented J an, 24;, 1922 1920. Serial No. 895,606.

Figure -3 is an enlarged fragmentary front elevation of the same; c

Figure 4 is a sectional side elevation of the improved automatic chucking machine on the line H of Figure 2, part of the vertical spindle head being shown broken away; v
